CATENA CON PEDALI SUL MOZZO DELLA RUOTA POSTERIORE” CHAIN WITH PEDALS ON THE REAR WHEEL HUB "

- Domanda divisionale su deposito n. 102017000044469 - - Divisional application on deposit no. 102017000044469 -

DESCRIZIONE DESCRIPTION

1) CAMPO DI APPLICAZIONE 1) FIELD OF APPLICATION

La presente invenzione trova applicazione nel settore tecnico B62K e ha per oggetto il dispositivo di piegamento di una bicicletta senza catena con pedali sul mozzo della ruota posteriore e dispositivo anti-impennata. The present invention finds application in the technical sector B62K and relates to the folding device of a bicycle without chain with pedals on the rear wheel hub and anti-wheelie device.

2) STATO DELLA TECNICA 2) STATE OF THE ART

Gli attuali sistemi di piegamento impongono all'utente l'esecuzione di più passaggi che incidono su più parti del telaio (manubrio, pedaliera, asse centrale). Vi è dunque un dispendio di tempo e di energie non indifferente. Current folding systems require the user to perform multiple steps that affect multiple parts of the frame (handlebar, pedal, central axis). There is therefore a considerable waste of time and energy.

3) ATTIVITA’ INVENTIVA 3) INVENTIVE ACTIVITY

La bicicletta della presente invenzione è dotata di un dispositivo originale molto più semplice, intuitivo e veloce, che riduce il tempo e l'energia richiesti per il piegamento a una piccola frazione rispetto alle biciclette attualmente in uso. The bicycle of the present invention is equipped with a much simpler, more intuitive and faster original device, which reduces the time and energy required for folding to a small fraction compared to the bicycles currently in use.

4) DESCRIZIONE TECNICA 4) TECHNICAL DESCRIPTION

4.1) Dispositivo per il piegamento della bicicletta. 4.1) Device for folding the bicycle.

Il dispositivo per piegare la bicicletta è situato tra i lati (9) e (11) del telaio. Su questi lati sono inseriti i due giunti mobili (13) e (14), la cui apertura è situata su un piano verticale, perpendicolare ai suddetti lati ed equidistante dai centri delle due ruote. Queste sono disposte in modo che la distanza tra i loro centri è costituita da due semidiametri più la semisomma della lunghezza dei perni dei loro mozzi (si intende che detti perni sono di uguale lunghezza e che il centro di ciascuno di essi coincide con il centro del rispettivo mozzo). Fra i medesimi lati (9) e (11) sono inseriti due perni filettati verticali (15) e (16) dentro i rispettivi mozzi (17) e (18). Questi ultimi sono connessi l'uno all'altro dal ferro piatto (19). Questo è composto da due parti uguali, ciascuna saldata al rispettivo mozzo, le quali nella parte centrale si sovrappongono parzialmente e sono imbullonate l'una all'altra come ultima operazione di montaggio del dispositivo. I mozzi (17) e (18) hanno la medesima lunghezza. I rispettivi perni vi sono installati con cuscinetti simili a quelli in uso nei mozzi delle ruote per evitare spostamenti assiali tra perno e mozzo. La posizione dei fori di inserimento del perno (15) sui lati (9) e (11) soddisfa la condizione che la retta verticale che ne costituisce l'asse sia tangente alla ruota posteriore. Analoga condizione vale per il perno (16) e la ruota anteriore, quando questa è allineata con il telaio. The bicycle folding device is located between the sides (9) and (11) of the frame. The two movable joints (13) and (14) are inserted on these sides, the opening of which is located on a vertical plane, perpendicular to the aforementioned sides and equidistant from the centers of the two wheels. These are arranged so that the distance between their centers is made up of two half-diameters plus the half-sum of the length of the pins of their hubs (it means that said pins are of equal length and that the center of each of them coincides with the center of the respective hub). Between the same sides (9) and (11) two vertical threaded pins (15) and (16) are inserted inside the respective hubs (17) and (18). The latter are connected to each other by the flat iron (19). This is composed of two equal parts, each welded to the respective hub, which in the central part partially overlap and are bolted to each other as the last assembly operation of the device. The hubs (17) and (18) have the same length. The respective pins are installed with bearings similar to those used in wheel hubs to avoid axial displacements between the pin and hub. The position of the holes for inserting the pin (15) on the sides (9) and (11) satisfies the condition that the vertical line which constitutes its axis is tangent to the rear wheel. The same condition applies to the pin (16) and the front wheel, when this is aligned with the frame.

Con le condizioni dette sino ad ora la distanza tra i perni (15) e (16) risulta uguale alla semisomma della lunghezza dei perni dei mozzi delle due ruote. Pertanto quando, per piegare la bicicletta, si piegano di 90 gradi le ruote posteriore e anteriore intorno ai rispettivi mozzi 15 e 16 , una in senso orario e l'altra in senso antiorario, i perni dei mozzi delle ruote vengono a trovarsi allineati e con le estremità a contatto. With the conditions described up to now, the distance between the pins (15) and (16) is equal to the half sum of the length of the hub pins of the two wheels. Therefore, when, to fold the bicycle, the rear and front wheels are folded 90 degrees around their respective hubs 15 and 16, one clockwise and the other counterclockwise, the hub pins of the wheels are aligned and aligned. the ends in contact.

4.2) Modalità del piegamento della bicicletta. 4.2) How to fold the bicycle.

Il piegamento della bicicletta si esegue, dopo avere aperto i giunti (13) e (14) e piegati i pedali (1), piegando le due ruote di novanta gradi, una in senso orario e l'altra in senso antiorario, mediante la rotazione dei perni (15) e (16) dentro i rispettivi mozzi. The bicycle is bent after opening the joints (13) and (14) and bending the pedals (1), by bending the two wheels by ninety degrees, one clockwise and the other counterclockwise, by turning pins (15) and (16) inside their respective hubs.

Il ciclista può eseguire questa operazione contemporaneamente con le due ruote, tenendo con una mano la sella e con l'altra il tubo dello sterzo, oppure spostando l'elemento (19) in senso perpendicolare al piano della bicicletta. Le ruote vengono così a trovarsi affacciate e parallele, con le estremità dei perni dei mozzi delle ruote a contatto sulla medesima retta, e sono tenute in posizione mediante un tirante elastico. La bicicletta può così essere condotta, mobile sulle sue ruote, in casa e fuori, sui mezzi pubblici e nei negozi. The cyclist can carry out this operation simultaneously with the two wheels, holding the saddle with one hand and the steering tube with the other, or by moving the element (19) perpendicular to the plane of the bicycle. The wheels are thus facing and parallel, with the ends of the wheel hub pins in contact on the same straight line, and are held in position by means of an elastic tie rod. The bicycle can thus be driven, mobile on its wheels, at home and outside, on public transport and in shops.
